This old 12" 4 jaw chuck appears very nicely made and from a decent material that has not rusted badly, but the only maker's stamp is on the jaws. Can anyone help identify the maker's insignia please?img_0698.jpg?

Its nice having the tee slots if a faceplate is required. I can only think of Toolmex, TOS and TGS chucks starting with a T, its strange that the jaws are marked, but not the body. There should be a serial number on the body to match the jaw numbers, maybe on the rear. 

If you are a member of one of the forums across the pond, they might know.

Someone has pointed out to me that the jaws are very likely not original to the chuck because the chuck jaw slot designations are in Roman Numerals whereas the jaws themselves are designated in English numerals. I have come round to guessing the unbranded chuck must be an old cheapo from China/Taiwan

Have you tried out the chuck on a lathe? Do the jaws fit well in the slots? I find it very difficult to believe that someone managed to assemble different manufacturers parts, especially as they don't seem to be in a worn condition.
